ONE-THIRD TO NICHOLAS BOX-FORMING APPARATUS.

Specification of Letters Patent.

Application filed September To all whom it may concern.'

Be it known that l, RUSSELL H. Birmania, a citizen of the United States, residing at New York, in the county of New York and State of N ew York, have invented new and useful Improvements in Box-Forming Apparatus, of which the following is a specification.

This invention comprehends the provision of a box forming apparatus, by means of which a box may be readily and easily formed from two separate Strips of paper, cardliioard or other suitable material.

he apparatus embodies among other features a male anvil member upon which the .strips of material from which the box is formed are arranged, and a cooperating female member which bends against the anvil in the formation of the box.

The invention also contemplates an improved method of forming a box from separable strips of material, the finished article being reinforced about the open end thereof by means of Wire or other suitable relatively stift" elements.

he nature and advantages of the invention will be better understood from the following detail description taken in connection with the accompanying drawing, the invention residing 1n the construction, combi- In the drawing forming part of this s ecification, like numerals of reference indicate similar parts in the several vievvs and Wherein:`

Figure 1 is a perspective view of the apparatus showing the initial arrangement of the strips from Which the box is formed, and the normal position of the cooperating members of the form.

Fig. 2 is a vertical sectional view through the male anvil member of the form showing the strips bent against the sides and subsequently bent upwardly constituting the second step of the operation.

Fig. 3 is a view similar to Fig. 2 illustrating the third step of the operation.

Fig. 4 is a fragmentary detail view showing the upper edge of the` box when completed.

The apparatus forming the subject matter coperating indicated at 11.

I atellted Oct. 5, 1920. 5, 1919. serial No. 321,742.

anvil member is mounted upon the base 12 and held stationary While the female member which receives the upper portion of the male member is movable toward and away from the latter. The male anvil member is of substantially rectangular formation, the sides however converging from an appropriate point in the height of the member toward the top 13 thereof. Each side of the male anvil member is provided with a horizontally disposed elongated slot 14 for a purpose to be hereinafter described. lt will be noted however, that the converging portion of each side merges into the straight portion thereof at a point in a plane with the transverse center of the 'l e female member 11 is supported immediately above the male anvil member by means of a yoke 15 terminally secured to the base 12 and straddling the anvil member 10. A tubular member 16 depends from the center of the yoke 15, for the reception of a rod 17 rising from the the female member, the rod passing through the yoke 15 and provided with a knob 18. A spring 19 encireles the tubular member 16 and has one end secured to the top of the female memits opposite end secured to the The spring is tensioned to northe female member 11 spaced 10 an appreciable yoke mally hold above the anvil member distance.

The apparatus described may be used in connection with the improved method of separate strips of paper or other suitable material indicated at 2U. In practice, the strips 2O are arranged in crossed relation as shown in Fig. 1 and may be secured together in this manner by suitable paper fasteners or the strips may be arrangeil in this manner to rest upon the top of the anvil 10 without being secured as shown in Fig. 1. Subsequent to the positioning of the strips 20 in this manner, the female member is forcibly driven down upon the conve ging portion of the anvil member 10, by impact against the knob 18, it being understood that the female member 11 is of similar configuration as the upper portion of the anvil member which it receives. Consequently, the projected extremities ofthe strips 20 are bent against the converging portions or sides of the mal(l anvil member 10. With the parts in this is placed about the position a single length ol relatively stiff material, such as wire or the like is wrapper about the downturned portion ol' the strips 20 and the male anvil member 10 at a point where the converging sides merge into the straight portion as shown in lfig. 2. ll' dosired, the wirr indicated at 2l may be first given a shape to conform to the configuration of the anvil meniber, and then slipped down over the anvil in the` downturned portion of the strips 20. 1n either instance however, the reinforcing element 3l occupies the position illustrated in Fig. 2, and the ends of the strips 2() are then bent up Wardly shown at 22. Prior to the placing of the reinforcing element about the down turned portions of the strips 20, the female member 'll may be allowed to return to its normal elevated position, or il' desired it may be constructed of sinh size as to be frictionally maintained associated with the male anvil member until lhc reinforcing member 2l has been placed in position illustrated in Fig. 2. 1f the female member ll is used in this manner. i` will seive to hold the sides of the strips 2|) taut against the adjacent sides of the anvil member 1l) until the reinforcing element is wrapped or otherwise properly placed about the downturned portions of the strips. After the extremities of the strips 20 have been turned up over the reinforcing element 21 as shown in Fig. Q, an additional reinforcing element similar to the element 21 but indicated at upturned extremities Fig. 3. It might here he stated, that one side of each strip QU is coated with an adhesive substance 24, and when the termin ls of the strips have been bent upwardly in the manner disclosed in Figs. 2 and 3, the adhesive side 2% of each strip is outermost. The reinfori. ing element Q3 effectively maintains the reinforcing element 21 confined between the folds of the strips, and when the reinforcing element 23 has been arranged in the manner as shown in Fig. 3, the terminale of the strip are then bent downwardly over the reinforcing element Q3, through the slots 14 and adhesively secured to the inner side of each strip. This arrangement is shown at the right hand side of Fig. 3, wheieinthe finally secured terminal of one strip is indicated at Q5. The slots 14 are of sullicicnt size to provide for the insertion of the fingers within the anvil member l0, and in order `to secure the terminals 25 of each strip against one side thereof. Obviously, the crossed portions of the respective strips constitute the bottom of the box, indicated at 26 while the bent portions constitute the sides of the box. When the box has been thus formed, it is removed from the anvil 10 and as shown in Fig. 4 the upper edge of the box is effectively reinforced by the elements 21 as illustrated in and Q3 which are embedded in the folds of the matt-rial from which the box is formed.

While it is believed that the nature and advantages of the invention will be readily apparent from the foregoing description, l desire to have it understood that l do not limit myself in this colu'iection and that such changes may be resorted to when desired as fall within the scope of what is claimed.

llaving thus described my invention what l claim as new is 1- 1. 1n a box forming apparatus, male and female members, means for normally hold ing said members separated, said male member having sides including straight portions and angularly disposed portions, one of said members being movable toward and away from the other, and said male member hav ing an elongated slot at each side.

2. ln a box forming apparatus, a malo anvil, a female member, ),icldablo means supporting the female member above said anvil, said ,female member being movable toward and away from said anvil, and said anvil having an elongated slot in each side thereof.

3. T he herein described method of forming a box, consisting of crossing two strips of material, and arranging said strips upon an anvil, then bending the projecting portions of said strips against the sides of the anvil, then surrounding said portions of the strip with a reinforcing element, and then bending the terminals of said strips against the latter and about the said reinforcing elements.

i. The hereinv described method of formr ing a box, consisting of crossing two strips of material, and arranging said strips upon an anvil, then bending the projecting portions of said strips against the sides of the anvil, then arranging a reinforcing element about the bent portions of the strip, then bending the strips upwardly and around the reinforcing element, then placing a second reinforcing element about the upturned ortions of the strip, and then finally ben ing the upturned portions over the second mentioned reinforcing element and adhesively securing the terminals against the inner sides of said strips.

5. In a box formi g apparatus, a base, male and female members, one of said members reposing upon the base, a yoke fixed on said base, the other of said members being suspended from said yoke and movable toward and away from the member reposing upon the base, and yieldable means interposed between said yoke and its associated member for normally holding the said mem bers separated.
